I have Vernatone MkI mufflers in my 31' Commander. Does anybody know how long these things actually last? From what I can see from the outside they look ok, but inside?
I don't know how old they are. They were in the boat when I bought her in 1998. Since then she has spent all summers in fresh water and winter on the hard. Before that she spent some years in Florida...
As far as I know they're all fiberglass. So corrosion shouldn't be a factor, should last as long as they don't crack. Even then I suppose you could get some cloth and resin to repair them.
No news is good news ! I have never heard of a Vernatone failure. Even some quicky internet research doesn't turn up any failures other than an occasional seam leak, easily repaired with fiberglass and resin. Even in salt water they seem to be bulletproof. I think they are a special formulation of fiberglass with some roving and chemical modifications to make them even stronger. I think the only thing that would damage them is a monstrous backfire right in the Vernatone. I'll bet a little fiberglass repair work would even fix a Vernatone blown apart by a large backfire.
Pretty nice product that will probably last as long or longer than it's Commander home. Good stuff Alarik. Don't worry about them :-)
